Psychoacoustic Investigations on Sound-source Occlusion

Efficient simulation of sound-source occlusion is needed in auditory virtual environments and remains an unsolved problem. In order to achieve this, the changes in psychoacoustical parameters accompanying the perception of sound-source occlusion have to be identified and understood. The impact of occlusion on localization of auditory events is investigated with the aid of listening tests. Binaural impulse responses are recorded for this purpose in an anechoic chamber, in which rectangular wood plates of different dimensions are used to represent the occluders.
